FIELD OF INVENTION

This invention relates to organic catalysts and cleaning compositionscomprising such catalysts; and processes for making and using suchcatalysts and cleaning products.

BACKGROUND OF THE INVENTION

Oxygen bleaching agents, for example hydrogen peroxide, are typicallyused to facilitate the removal of stains and soils from clothing andvarious surfaces. Unfortunately such agents are extremely temperaturerate dependent. As a result, when such agents are employed in coldersolutions, the bleaching action of such solutions is markedly decreased.

In an effort to resolve the aforementioned performance problem, theindustry developed a class of materials known as “bleach activators”.However, as such materials rapidly lose their effectiveness at solutiontemperatures of less than 40° C., new organic catalysts such as3,4-dihydro-2-[2-(sulfooxy)decyl]isoquinolimium, inner salt weredeveloped. In general, while such current art catalysts are effective inlower temperature water conditions, they can inactivate certain enzymesand the more effective catalysts tend to be hydrophobic—thus theiraqueous solubility is limited. As most laundry and cleaning compositionsare formulated in, or intended to be used with water, formulatingcleaning products with such catalysts can be problematic.

Accordingly, there is a need for an inexpensive organic catalyst thatcan provide the combined benefits of formulation flexibility, and lowwater temperature bleaching performance.

Processes of Making Organic Catalysts

Suitable routes for preparing Applicants' organic catalysts include, butare not limited to, the synthetic routes detailed below:

Alcohol 1 may be converted to halohydrin 2 via Lewis acid catalyzedaddition to epihalohydrin, followed by (a) base induced ring closure toepoxide 3 and subsequent ring opening with HX, or (b) halogen exchangereaction. Halohydrin 2 may be converted to product 5 by (1) alkylatingdihydroisoquinoline 9 and then sulfating (2 to 6 to 5), or (2) sulfatingand then alkylating 9 (2 to 8 to 5). Alternatively, the product may beobtained from epoxide 3 via (1) conversion to cyclic sulfate 4 andreaction with dihydroisoquinoline 9, or (2) Lewis acid catalyzedaddition to 9 to form oxazolidine 7 which is opened under acidicconditions to 6 and subsequently sulfated. While the synthetic pathwaysdetailed above employ specifically substituted reagents, as will beappreciated by one skilled in the art, reagents with differentsubstituents may be employed if other products are desired.

Raw materials required for the aforementioned syntheses are generallycommercial available. For example, glycidal ethers such as(2-ethylhexyloxy)oxiran-2-ylmethane can be acquired through the RaschigCorporation, 129 South Scoville Avenue, Oak Park Ill., 60302, U.S.A,under the product name EHGE. 3,4-Dihydroisoquinoline can be prepared bythe Bischler-Napieralski reaction, as described by Whaley et al (W.Whaley et al, Organic reactions (1951), VI 74-150). Halohydrins, such as1-Bromo-3-(2-ethyl-hexyloxy)-propan-2-ol and cyclic sulfates such as4-[(2-ethylhexyloxymethyl]-1,3,2-dioxathiolane-2,2-dione can be preparedby the detailed procedures described in Applicants Examples.

The synthesis paths that Applicants' developed allow commercialquantities of cyclic sulfate to be produced using falling film reactorswherein cyclic sulfate is produced by the process of: 1.) introducingthe appropriate glycidal ether into a dry stream of SO₃ gas, 2.)contacting said reagents within the falling film reactor, 3.) thenoptionally holding the resulting reaction mixture at a sufficienttemperature for a sufficient time to achieve the desired conversion, and4.) optionally isolating the resulting cyclic sulfate. As appreciated bythe skilled artisan, reaction conditions vary depending on equipmenttype. However, when in possession of the teachings contained herein,such conditions are easily determined.

Commercial quantities of Applicants' catalyst can be produced using avariety of reaction vessels and processes including batch, semi-batchand continuous processes. Non-limiting procedures for producingApplicants catalyst include contacting glycidal ether with an SO₃complex, either neat or with an appropriate aprotic solvent for lessthan about 60 minutes, at a temperature of from about 75° C. to about130° C., and a pressure of about 1 atmosphere to form the desired cyclicsulfate. Final conversion to the desired organic catalyst is achieved bycontacting the cyclic sulfate with a 3,4-dihydroisoquinoline for lessthan about 24 hours, at a temperature of from about 20° C. to about 50°C., and a pressure of about 1 atmosphere.

In addition to the procedure described above, Applicants' catalyst canbe produced by first producing a halohydrin, such as 1-bromohydrin, bycontacting a glycidal ether with hydrobromic acid for less than about 10minutes, at a temperature of from about 0° C. to about 40° C., and apressure of about 1 atmosphere, and then isolating the 1-bromohydrinthrough conventional means that include but are not limited toextraction and distillation. Next the 1-bromohydrin is reacted with a3,4-dihydroisoquinoline for about 48 hours, at a temperature of about40° C. and a pressure of about 1 atmosphere to form alcohol salt whichis subsequently sulfated in the same reaction vessel via a sulfatingagent such as SO₃, an SO₃ complex, HSO₃Cl or mixture thereof to generatethe desired product.

The oxaziridinium ring containing version of Applicants' catalyst may beproduced by contacting an iminium ring containing version of Applicants'catalysts with an oxygen transfer agent such as a peroxycarboxylic acid.Such species can be formed in situ and used without purification.

Example 18 Method of Preparing a Starch Encapsulated Particle Comprisingthe Applicants' Organic Catalyst

151 g of the Applicants' organic catalyst according to any of Examples1-11 above was slowly added to 7,550 g of an aqueous starch solution (33wt % solids) in a high-shear mixer for 2 minutes. 190 g of sodiumcarbonate (which is dissolved in 498 g water) is added to this mixture,and the resulting mixture is mixed for 5 minutes in a high-shear mixer.This mixture is then spray dried using a Drytec Compact spray Drier™with an inlet temperature of 190° C. and an outlet temperature of 90°C., and with the exhaust fully open to form a starch encapsulatedparticle comprising 4.9 wt % Applicants' organic catalyst, 81 wt %starch, 6.2 wt % sodium carbonate and 7.9 wt % water.
